Internal friction in the particulate magnetoelectric composite (x)PbZr0.53Ti0.47O3–(1 − x)Mn0.4Zn0.6Fe2O4

Abstract: The internal friction and shear modulus for the particulate magnetoelectric composite (x)PbZr0.53Ti0.47O3–(1 − x) Mn0.4Zn0.6Fe2O4 have been studied over a temperature range from room temperature to 670 K. In the vicinity of the ferroelectric phase transition temperature, we have observed the internal friction peak that is explained in terms of the fluctuation model. The “residual” internal friction near the ferroelectric Curie point has also been revealed. The “residual” internal friction is assumed to be due … Show more

“…As it follows from Equation , the height of the Q −1 maximum is directly proportional to trueT˙ and inversely proportional to f . Similar regularities were observed by authors earlier . Consequently, the fluctuation loss mechanism contributes to the internal friction in the composite near T C .…”
